The aviator-style Julbo Chrono polarized photochromic sunglasses are a classic pick for road trips, lounging by the pool or strolling outside in changing weather. Falcon(R) polarized photochromic NXT lenses respond quickly to changing light conditions, darkening in bright light and lightening in dim light. Falcon lenses are multipurpose and recommended for driving; lenses are sensitive to visible light and will darken behind a windshield. Polarized lenses reduce 99% of visible glare from water, snow, sand and pavement for increased visual acuity and decreased eye strain. NXT polyurethane lens material provides exceptional optical clarity and visual comfort. Extremely flexible and impact resistant, NXT lenses are guaranteed not to break or crack. Brown lens tint cuts down on overall brightness without distorting colors. Anti-reflective coating reduces eye strain; oil-repellent coating prevents grease marks from fingers, hair and sunscreen. Durable, lightweight metal frames feature flexible temples and adjustable nosepieces that accommodate a wide variety of face shapes. Julbo Chrono sunglasses include a protective case.
